Where can you run Oracle APEX https://www.oracleapextrainer.com/ Oracle Cloud: You can run APEX in an Autonomous Database (ADB) – an elastic database that you can scale up. It’s self-driving, self-healing, and can repair and upgrade itself. It comes in two flavours: Autonomous Transaction Processing (ATP) – basically transaction processing, it’s where APEX sees most use; Autonomous Data Warehouse (ADW) – for more query-driven APEX applications. Reporting data is also a common use of Oracle APEX. You can also use the new Database Cloud Service (DCS) – an APEX-only solution. For a fee, you can have a commercial application running on a database cloud service
Where can you run Oracle APEX https://www.oracleapextrainer.com/ On-premise or Private Cloud You can also run Oracle APEX on-premise or in a Private Cloud – anywhere where a database runs. It can be a physical, dedicated server, a virtualized machine, a docker image (you can run it on your laptop, fire it up on a train or a plane – it’s very popular among Oracle Application Express developers). You can also use it on Exadata – a super-powerful APEX physical server on cloud services.
With Autonomous Database Included with New Always Free Service https://www.oracleapextrainer.com/
Architectural Overview Oracle APEX uses a simple 3-tier architecture where requests are sent from the browser, through a web server, to the database. All processing, data manipulation and business logic is executed in the database. This architecture guarantees zero latency data access, top performance, and scalability, out of the box. https://www.oracleapextrainer.com/

Oracle APEX is a feature of Oracle Database, thus if you have a license for Oracle Database, you already have Oracle APEX. Flexibility With Oracle APEX you have a lot of flexibility with where you do development, from developing on a laptop, on-premises, or in the cloud. Where you develop your apps doesn't limit where you can deploy your applications. You can develop and deploy wherever there is an Oracle Database, with Oracle APEX installed. No need to install any desktop client for application development. Just need web browser for everything.
